No cube rotations during a solve, more freedom when creating blocks (similar phase to F2L in CFOP), you can use the M slice to your advantage during the whole solve, less algs and more intuitive in general.
On the other hand turns can be less fluid and the solve is less algorithmic which hinders the speed.
I’m not good enough at either of the methods to actually say which is better, but I would say it is easier to get fast with CFOP
What are the advantages of roux (over CFOP)?
